Thailand has recently implemented regulatory changes in the cosmetics industry, introducing a new list of prohibited ingredients and updating the requirements for permitted preservatives. These updates align Thailand's regulations with the latest ASEAN Cosmetic Directive revisions.
On June 22, 2023, the Ministry of Public Health of Thailand (MOPH) issued three notices through the 140th Government Gazette of 2023, detailing the regulatory revisions pertaining to prohibited ingredients and permitted preservatives in cosmetics. These notices officially came into effect on June 23, with a transition period applying to some rules.
The key amendments are as follows (Additions or revisions to the previous lists are indicated in red, while removals are indicated by strikethrough):
1. New Prohibited Ingredient List
Thailand has issued a new List of Prohibited Ingredients in Cosmetics to replace the previous version published in 2016. This updated list incorporates all the modifications made by the Thai MOPH from 2016 to 2022, and includes additional 220 prohibited ingredients, totaling 1,610 substances.
Below are a few examples of the newly added prohibited ingredients:

Chemlinked Comments
Thailand’s addition of 220 prohibited ingredients aligns with the updates made to the prohibited ingredients list of the ASEAN Cosmetics Directive (ACD), as adopted during the 34th ASEAN Cosmetic Scientific Body (ACSB) meeting. Similarly, the revisions to the use requirements for the two permitted preservatives are consistent with the updates made to the preservatives list in the ACD, adopted at the 35th ACSB meeting.
However, it is noteworthy that Thailand has implemented additional restrictions concerning the banned ingredient silver nitrate, distinguishing its requirements from those of the broader ASEAN region. Specifically, while silver nitrate is permitted for use in hair dye cosmetics exclusively for export purposes, Thailand prohibits export-oriented cosmetics containing silver nitrate sold at home.
